DOOR STRUCTURE Filed June 9, 1931 A TTORNEYS.

Patented May 5, 1936 UNITED STATES PATENT OFFICE DOOR STRUCTURE Application June 9, 1931, Serial No. 543,118

2 Claims.

In many door structures, such as the doors of ovens, cookers, cold storage and refrigerator doors, etc. it is desired to maintain a sealed connection between the door and the door seat.

Ordinarily this is accomplished by providing one of the seating faces with a yielding material and as the door is used the seating material wears, or recedes from its original position and when this happens a complete seal is finally lost. The present invention is designed to provide an adjustable means for the door whereby adjustment may be made for yielding or variation in the seating material. Features and details of the invention will appear from the specification and claims.

A preferred embodiment of the invention is illustrated in the accompanying drawing as follows:

Fig. 1 shows a front view of the structure.

Fig. 2 a section on the line 2-2 in Fig. 1,

Fig. 3 a section on the line 3-3 in Fig. 1.

Fig. 4 a perspective view of one of the hinge connections.

Fig. 5 a perspective view of the adjustable hinge block.

I marks the door frame. This has a door open ing 2 surrounded by a raised seat 3. A door 4 is provided with a groove 4a in which is placed a gasket, or seating material 417.

The door is provided with hinge knuckles 5. A hinge mounting bar 6 is secured to the frame by screws 1. Loops 8 extend outwardly from the bar 6, said bar forming a support for the loops. The loops form slots 9 receiving hinge blocks 35 ID, the sides of the slots forming guide surfaces for the blocks. The hinge blocks slide in and out in the loops, or in other words, toward and from the frame. The blocks have grooves Illa and the blocks are locked in the loops by screws H which extend into the grooves Illa holding the blocks in the slots 9, and when they are adjusted lock them in adjustment by engaging the inner wall of the groove. A screw [2 extends through the outer end of the loop and is adapted 45 to adjust the block toward and from the frame. .A hinge pintle l3 extends through the knuckles and the blocks. It is provided with a head M which prevents it from dropping through the knuckles and blocks.

The door is provided with a cam latch surface I5 and a latch l6 has a projection [1 which extends through a screw-threaded sleeve l8. A nut l9 secures the projection in the sleeve and the nut is locked in place by a cotter pin 20. The 5 sleeve I8 operates in a screw-threaded opening 2| and is locked in adjustment by a nut 22. It will readily be seen that by adjusting the sleeve the latch may be adjusted toward and from the frame and the sleeve may be locked in whatever 10 adjustment it may be extended to by the lock nut. It will also be observed that by adjusting both the hinge and the sleeve the door may be kept in proper relation to the seat on the frame and a perfect seal maintained between the gasket 15 and the seat. I preferably make the opening 2! of sufficient diameter to permit the entrance of the nut 19 so that the handle with the sleeve assembled may be run into place. If, therefore, there should be any loosening of the nut the 20 sleeve may be readily removed and the nut adjusted. A stop pin 24 is provided which is engaged by the handle as the handle is thrown to open position.

A set screw 23 is provided locking the pin 25 with the knuckle of the door. In consequence all wear is between the pin and the block and should wear take place all that is necessary is to renew the pin and the block to secure complete alinement.

What I claim as new is:-

1. A hinge structure comprising a hinge loop having opposing guide surfaces; a hinge block slidingly mounted in the loop in engagement with said guide surfaces; a hinge knuckle; a pintle connection between the block and knuckle; an adjusting screw for adjusting the block in the loop; and a screw operating against the side of the block locking the block in adjustment.

2. A hinge structure comprising a hinge loop having guide surfaces therein; a hinge block slidingly mounted in the loop in engagement with the surfaces, said block having a guide groove therein; a hinge knuckle; a pintle means connecting the block and the knuckle; and a screw extending into the groove holding the block slidingly in the loop and adapted to lock the block in adjustment.
